Abstract

A water-cooling device for cooling a heat-generating element within an electronic apparatus. The water-cooling device includes a water-cooling jacket which is thermally connectable with the heat-generating element, a heat-radiation pipe, a tank, and a liquid driver which forms a circulation flow passage through which a cooling liquid flows. At least one of the water-cooling jacket, the heat-radiation pipe, the tank and the liquid driver is attached on a plate, and the water-cooling device is detachable with respect to the heat-generating element by the plate.

1 . A water-cooling device for cooling a heat-generating element within an electronic apparatus, comprising: 
 a water-cooling jacket which is thermally connectable with the heat-generating element;    a heat-radiation pipe;    a tank; and    a liquid driver which forms a circulation flow passage through which a cooling liquid flows;    wherein at least one of the water-cooling jacket, the heat-radiation pipe, the tank and the liquid driver is attached on a plate, and the water-cooling device is detachable with respect to the heat-generating element by the plate.    
   
   
       2 . A water-cooling device for cooling a heat-generating element within an electronic apparatus, comprising: 
 a water-cooling jacket which is thermally connectable with the heat-generating element;    a heat-radiation pipe;    a tank; and    a liquid driver which forms a circulation flow passage through which a cooling liquid flows;    wherein at least one of the water-cooling jacket, the heat-radiation pipe, the tank and the liquid driver is attached on a plate, and the water-cooling device includes a piping system for circulating the cooling liquid which contains an anti-freeze fluid therein, the piping system of the water-cooling device being received within a case of the electronic apparatus as a unit so as to be detachable therefrom, and wherein the cooling liquid which contains the anti-freeze fluid is collectable at least in the tank.
